Point is located at and adopts on a yard window (31)；Electricity on the two-dimensional code identifier, the light that luminescence unit sends is through adopting after a yard window (31)
Reach local code-point；The light reflected by local code-point reaches half-reflecting half mirror (32) afterwards by adopting a yard window (31)；Half anti-half
Lens (32) are reflected to a part of light for receiving, and the light after refraction is gathered by imaging sensor (33)；Half anti-half
Lens (32) are reflected to another part light for receiving, and the light after reflection is reached by through hole (7) and is located at the first chamber
On the speculum (41) of room (5)；Under the reflex of speculum (41), light moves on along reflection path, final logical
Cross form (42) and reach human eye, so far, eye-observation is to positioned at the code-point situation that adopts in a yard unit (3)；
S3, human eye pass through the code-point situation that observes, moving 2 D code recognizer adjusts the position of gathered target code-point,
Until making collected Quick Response Code be located at the best region for adopting a yard unit (3)；
S4, due to collected Quick Response Code and adopts a yard unit (3) close contact, be collected Quick Response Code to imaging sensor (33) away from
A yard unit (3) is adopted to a distance from imaging sensor (33) from being equal to, focal length is, then：Collected Quick Response Code blur-free imaging to into
As on sensor (33), imaging sensor (33) is by the clearly image in 2 D code for collecting by communications interface transmission to upper
Machine；
Wherein, in S2, under the reflex of speculum (41), light moves on along reflection path, eventually through form
(42) reach human eye to be specially：
Under the reflex of speculum (41), light moves on along reflection path, is made by the amplification of lens group (43)
With rear, human eye is reached eventually through form (42).
